Mix Cellini (which he pronounces with an 'S' rather than a 'C') is superstitious about the number 13. In the musty old house where he is the lodger, there are thirteen steps down to the landing below his rooms, which he keeps spick & span. His elderly landlady, Gwendolen Chawcer, was born in St Blaise House, & lives her life almost exclusively through her library of books, so cannot see the decay & neglect around her. The Notting Hill neighbourhood has changed radically over the last fifty years, & 10 Rillington Place, where the notorious John Christie committed a series of foul murders, has been torn down. Mix is obsessed with the life of Christie & his small library is composed entirely of books on the subject. He has also developed a passion for a beautiful model who lives nearby
- a woman who would not look at him twice. Both landlady & lodger inhabit weird worlds of their own. But when reality intrudes into Mix's life, a long pent-up violence.
